Summary: A series of CaAlSiN3:Ln (Ln=Eu, Ce, Dy, Pr, Tb, Gd, Sm, Tm, Nd) phosphors were successfully prepared by combustion synthesis, and their polychromatic visible afterglow emissions were observed. CaAlSiN3:Eu2+ and CaAlSiN3:Ce3+ showed the best red and yellow long persistent luminescence with persistent times of 4980 s and 4860 s, respectively. Eu2+, Ce3+ co-doped CaAlSiN3 exhibited enhanced red long persistent luminescence with a persistent time of 6300 s, attributed to a more appropriate trap depth distribution.

Summary: Fluorine-containing rare earth compounds of the LiLn(4)Mo(3)O(15)F composition were synthesized using solid-phase synthesis. Luminescence, hygroscopic, and electrophysical characteristics of the LiEu4Mo3O15F phase were studied for the first time. The replacement of europium with lithium and oxygen with fluorine led to a reversible phase transition and a significant increase in conductivity. The size of the Ln cation was found to affect the hygroscopic and conductive properties of LiLn(4)Mo(3)O(15)F compounds.

Summary: The study proposes a novel strategy to achieve solid-state luminescence turn-on sensing by assembling reporter-spacer-receptor (RSR) architectures within MOF frameworks. Unlike regular RSR systems, the framework-confined fluorophore and receptor are well arranged and separated even in the solid state. This study demonstrates a sensitive solid-state luminescence turn-on probe for phosphate by utilizing a multicomponent MOF (Fc@NU-1000) with a quencher displacement-based RSR system, offering new opportunities for MOF materials in developing luminescence turn-on sensors.
